Objective: Using spatial autocorrelation analysis to study spatial distribution characteristics of pneumoconiosis in China. Methods: The incidence of pneumoconiosis of each province from 2009 to 2013 was calculated by reported data of pneumoconiosis and the number of employment in mining and manufacturing of each province from Chinese statistical yearbook. The global and local spatial autocorrelation analysis was im-plemented by global and local's Moran's I index respectively. Results: A total of 112 066 new cases of pneumo-coniosis were reported from 2009 to 2013 in China, Global Moran's I from 2009 to 2013 was -0...

OBJECTIVE: The Japanese government established the Pneumoconiosis Law in 1960 to protect health and promote the welfare of workers engaged in dust-exposed works. This article describes Japanese practice in workplace health management as regulated by the Pneumoconiosis Law to reduce pneumoconiosis in Japan. METHODS: We collected information addressing pneumoconiosis and the health care of dust-exposed workers. We included all types of scientific papers found through a PubMed search as well as official reports, guidelines, and relevant laws published by the Ministry of Health, Labour and Welfare (MHLW) of Japan and other academic institutions...

Coal workers' pneumoconiosis, also known as "black lung disease," is an occupational lung disease caused by overexposure to respirable coal mine dust. Inhaled dust leads to inflammation and fibrosis in the lungs, and coal workers' pneumoconiosis can be a debilitating disease. The Federal Coal Mine Health and Safety Act of 1969 (Coal Act),* amended in 1977, established dust limits for U.S. coal mines and created the National Institute for Occupational Safety and Health (NIOSH)-administered Coal Workers' Health Surveillance Program with the goal of reducing the incidence of coal workers' pneumoconiosis and eliminating its most severe form, progressive massive fibrosis (PMF),(†) which can be lethal...

BACKGROUND Accumulating evidence shows that functional impairment in subjects with coal workers' pneumoconiosis (CWP) is principally due to emphysema and airflow obstruction, rather than underlying restrictive mechanisms. However, cigarette smoking has remained a major confounder. The aim of this study was to assess whether coal dust exposure was associated with emphysema and/or airflow obstruction in the absence of smoking history. MATERIAL AND METHODS The subjects evaluated for possible pneumoconiosis between 2013 and 2015 were retrospectively enrolled into this study...

During the last 1.5 years an update of the guideline on silicosis was made by an interdisciplinary working group. New medical and scientific knowledge and the experience in expert opinion practice were taken into account.By preparing the initial guideline in 2010 standardization of diagnostics and adaption of the "Moers convention" which was not based on medical knowledge was in the focus, whereas the current update deals with fine emendation and extension, especially of the compensation rate (adaption with the Reichenhall recommendation)...

OBJECTIVES: To construct a phage display human antibody library (PDHAL) against pneumoconiosis for the diagnosis and treatment of coal worker pneumoconiosis (CWP). METHODS: The PDHAL was established via CWP blood and six positive antibodies were discovered. 867 coal workers (558 CWP and 309 without CWP) and 393 controls were recruited to validate the results. RESULTS: A PDHAL against CWP was established, from which six strong positive clones were selected, sequenced and identified as VEGF, interleukin-18, HSP70, HER3, Gz-B and RF...

Objective: To investigate the prevalence of pneumoconiosis in a coal enterprise, and to provide a basis for the prevention and treatment of pneumoconiosis. Methods: The workers' occupational health examination data were collected, and a cross-sectional study was performed to analyze the prevalence of pneumoconiosis. Results: A total of 62 976 person times of occupational health examination were performed for the workers exposed to dust in this enterprise from 2002 to 2013. There were 8 445 cases of pneumoconiosis diagnosed in total, and the mean detection rate was 13...

Objective: To investigate the application of principal component analysis in comprehensive indicator screening for pneumoconiosis in different regions. Methods: A principal component analysis was performed for the data of 11 factors associated with the prediction of pneumoconiosis hazard and collected in the investigation on occupational health status conducted in 172 counties (districts) in Hebei, China. The degree of pneumoconiosis hazard in different regions was obtained and intuitively presented by GIS...

Objective: To investigate the value of low-dose multi-slice CT (MSCT) chest scan in the diagnosis of coal workers' pneumoconiosis. Methods: A total of 90 patients with a confirmed diagnosis of coal workers' pneumoconiosis were enrolled, and under the conditions of fixed tube voltage, pitch, and slice thickness, they underwent CT scan with a normal dose (150 mA) and a low dose (30-50 mA). The quality of images obtained from two scans was compared, and the imaging findings, opacity profusion, stage, and radiation doses were also compared...

OBJECTIVE: To characterize the chest radiographic findings of pneumoconiosis in a New Mexican cohort of uranium workers. METHODS: The most recent results from chest radiographs were abstracted in this cross-sectional study. RESULTS: Radiographs showed small pneumoconiotic opacities of profusion score of ≥ 1/0 in 155/429 (36...

BACKGROUND: Exposure to respirable crystalline silica (RCS) causes emphysema, airflow limitation and chronic obstructive pulmonary disease (COPD). Slate miners are exposed to slate dust containing RCS but their COPD risk has not previously been studied. AIMS: To study the cumulative effect of mining on lung function and risk of COPD in a cohort of Welsh slate miners and whether these were independent of smoking and pneumoconiosis. METHODS: The study was based on a secondary analysis of Medical Research Council (MRC) survey data...

Carbon nanotubes (CNTs) are newly developed materials with unique properties and a range of industrial and commercial applications. A rapid expansion in the production of CNT materials may increase the risk of human exposure to CNTs. Studies in rodents have shown that certain forms of CNTs are potent fibrogenic inducers in the lungs to cause interstitial, bronchial, and pleural fibrosis characterized by the excessive deposition of collagen fibers and the scarring of involved tissues. The cellular and molecular basis underlying the fibrotic response to CNT exposure remains poorly understood...

In 1974, the National Institute for Occupational Safety and Health recommended a ban on the use of silica sand abrasives containing >1% silica due to the risk of silicosis. This gave rise to substitutes including coal slag. An Occupational Safety and Health Administration investigation in 2010 uncovered a case cluster of suspected pneumoconiosis in four former workers at a coal slag processing facility in Illinois, possibly attributable to occupational exposure to coal slag dust. This article presents the results from a National Institute for Occupational Safety and Health industrial hygiene survey at the same coal slag processing facility and a second facility...

AIM: Pneumoconiosis is caused by inhaling dust. The aim of the study was to analyze 208 cases of workers' pneumoconiosis. METHOD: Patients' files were used for the descriptive study. RESULTS: All patients were male aged 38.82±13 years. The most important symptom was breathlessness. Patients were denim sandblasters (50.5%), dental technicians (12%), coal miners (6.7%), and others. The mean exposure time before pneumoconiosis occurred was shorter in denim sandblasters and teflon kitchenware producers compared to other occupations (5...

REVIEW

Occupational lung diseases span a variety of pulmonary disorders caused by inhalation of dusts or chemical antigens in a vocational setting. Included in these are the classic mineral pneumoconioses of silicosis, coal worker's pneumoconiosis, and asbestos-related diseases as well as many immune-mediated and airway-centric diseases, and new and emerging disorders. Although some of these have characteristic imaging appearances, a multidisciplinary approach with focus on occupational exposure history is essential to proper diagnosis...
